'1,- all whom it may'conce'm:

Be it known that I, Louis A. KRAMER, a citizen of the United States of America, residing at the city of St. Louis, State of illssouri, have invented a certain new, and 'useful Carcass Scraping and Polishing Machine, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being hadto the accompanying drawings, forming part of this specification. w

This invention relates to improvements in ca 'cass scraping and polishing machines of the type inwhich thc carcass isloosely supported, rotated and advanced in operative relation with scraping and polishing apparatus Without the use of hooks or other devices attached to the carcass, and, more specifically relates to improvements in machines of the character descril'ied in Kohlhepp Patent No. 1,0125%.

In the operation of the liohlhepp niachine, it has been found that notwithstand ing the downward inclination of the axis oi the rotating cylinder which supports and s designed to rotate and advance the carcass pas+u the contained'beater shaft, that carcasses sometimes tend to progress bacl:- Wardly toward the receiving end of the cyl- J der. This result is no doubt this to the ct that the carcass assumes a position at such an angle to the axis of the cylinder that when rolled on the cylindefs-inuer surface, its change of position on this surface will be in the direction of the receiving end of the cylinder, notwithstanding the fact that this end is higher than the discharge end.

it is to the provision of means for overcoming the condition just descrioed and to keeping all carcasses in proper position to insure their advancement through the machine, that this invention is particularly directed.

in the accompanying drawings, which illustrate one embodiment of my invention,- igure 1- is a side elevation of anachine of. the type referred to; Fig. 2 is an nd elevation; and Fig. 3, a view partlyin section showing the rotating conveyor and contained polishing device.

1 The cylinder conveyor 1 rests on roller s 2,, supported on a suitable 55.

frame," and is rotatedtroin the shalt 21' by means the -the outer end 7 19, it being understood that the particularprovided with members scraping and is simultaneously pinion 3 which meshes with the gesligjteeth i on the periphery of the cylinder. The conveyer is prefer-a ly inclined, as shoivhg and suitable rollers such as 5 are positioned in the path of the lower end of the cylinder'tto prevent longitudinal movement. Extending through the cylinder is the shaft 6 to WhichF are attached heaters or heaters are preferably flexible and may be constructed of heavy canvas or other suitable material,

with metal scraping members form and construction of the boaters or scrapers 3' form 110 essential part of my invention. The heater shafto is actuated by means of sprockets 8 and 9, and chain 10, the sprocket Wheel 8 illustrated, being on the same shsit as the pinion 3 by means of which the cylinderis rotated. lVit-h'this arrangement, the cylinder and beater shaft are actuated in opposite directions. i

Adjacent to the receiving end of the cylinder is the scalding tub ll and the conscrapers 7. These I and are usually provided near in the cor .ructidn veyer 12, by means of which carcasses may conveyed froin'the scalding tub into the cylinder.

13 is aportion of a bench upon Which the carcasses may be discharged. a By means or the pump 14. and the pipe 15, hot water is conveyed from the tank 16, into thecylinder and sprayed upon the car- This water and-much of the hair" removed from the carcass is discharged from the cylinder through the slots 22, the

water returning to the tank 16 and the hair being caught by the screen-17. The pump andthe conveyor 12 are driven from the shaft 21 in the manner shown. The interior Wall of the cylinder may be l8'to assist in turn ing the carcass. These members 18 maybe of any suitable pitch orstraight and extending parallel with the axis of the cylinder.

Theo-peration of the machine in. scraping and polishing hogs will now he. described.

it will be noted in Fig. '3 that, "While the cylinder conveyor is shown as inclined horizontally; the beater shafts is level and the heaters themselves extend a} substantially uniform distance rediall' from this shaft. When the carcass "is de ivered intothe machine, the heaters strike it and it rotated on account of the turning of the conveyer and thus all parts of the carcass are successively exposed to the operation of the scrapers. It will. be noted, howeven that on account of the inclination of the cylinder with reference-to the beater shaft, the portion of thecarcass nearest the receiving end of the machine Will be struck by the heaters at a lower point than other heaters are simultaneously striking the carcass with the result that a greater displacing effect will be exerted on one end of the carcuss than on the other. Referring to Fig. 2 and assinning that the cylinder driven in a countor-clockwise direction, as seen from the delivery end of the lIlikCl'llllQ, the heaters being simultaneously driven in a clockwise dircction,-should the portion of the carcass nearest the Iecehtiiig end of' the machine tend, for any reason, as it is rolling over and over on account of the rotation of the cylinder, to get intoa position at the right of the axis of the cylinder, while the other end of the carcass is either directly under the axis or somewhatat the left of the axis, then the carcass will progress backward,

thatis, approach the receiving end of the machine. But, the heaters are always striking theportion of the carcass nearest the receiving" end of the machine in such a directicn as to oppose tlliijlSSUlllPtlOll by the carcass of the position just described, and the heaters Which are simultaneously operating onthe other end of the carcass, While having a tendency to displace the carcass in the same direction as the first named boaters, do not have the same degree of, influence because they strike the carcass at a higher point. In my machine, the heaters, therefore, operate to either keep the axis of the carcass in the plane of the axis of the cylinder or to lrecp the portion of the carcass nearest the receiving end of the cylinder 21 little to the left of the portion nearest the discharge end of the cylinder (still viewing the apparatus from the discharge end as shown in Fig. 2). In this last named position, the hog vrould'advance through the cylinder in the direction desired even if the cylinder were level. Since the hog is pre vented, in my improved. machine, from assuming and maintaining an improper position while passing through the HlELOllll'lB, the p rpose of my invention is accomplished.

am aware that modifications may be made in the machine illustrated Without .departing from the principle of my invention. Ltherefore, do not intend that the scope o1 my invention shall be limited otherwise than by the appended claims.

Having fully described my invention, What I claim as new and desire to secure by Letters-Patent of the United States is:

In a carcass de-hairing apparatus, an inclined, rotatable, hollow conveyor for loosely supporting, rotating and advancing a carcass carcass scraping members distributed Within the conveyor and so arranged that, in operation of the apparatus, the scrapin znen'ibers vill themselves tend to maintain the carcass in suitable position with reference to the axis of the conveyor to facilitate its advancement by said conveyor.

(3. in a hog de-hairing machine, a rotatable member for conveying a carcass, and a scraping device in operative relation with the. carcass as it passes alongthe conveyor, said scraping device being; adapted to exert, in operation, a greater displacing effect upon one end of the carcass than on. the other.
